Latest Patents

Ali Massoumi holds a patent for a groundbreaking invention titled "Column redundancy based on column slices." This patent addresses the improvement of circuit redundancy in DRAM systems. The invention involves the use of global column lengths and the division of memory into groups with redundancy columns. When failures are detected among the slices of corresponding storage, they are replaced by the corresponding redundancy column slice. This method ensures that column redundancy division occurs in a vertical column direction. The design includes a global data line shared by column slices and multiple blocks. Additionally, redundant control circuits or comparators are positioned near data sense amplifiers. The system utilizes non-volatile memory or laser-blown or electrically-programmable fuses to provide defective column addresses to the controller. When a column address is presented, the incoming address is compared with the stored address, allowing for the output of select data on the redundant data line when equal addresses are detected.
